[ fixes several utf8/pango related problems, including bugs
#41288, #42596, #42604 ]
* configure.in (GAL_CURRENT): bump to 3, per mkestner.
(GAL_REVISION): drop to 0, per mkestner.
* gal/e-text/e-text.c (reset_layout_attrs): we need to convert the
start/end bounds of the object to byte indices for the attribute.
(reset_layout): in the layout == NULL case don't create the layout
then immediately set it again with the same text. also, we need
to convert selection_start to a byte index before calling
pango_layout_get_cursor_pos.
(e_text_draw): remove some #ifdef 0'd code, move the calculation
of our initial clip_rect below the xpos/ypos assignments so we
don't duplicate the expression. Fix the selection drawing in the
multiline case so that it actually works, instead of assuming that
all ETexts only have 1 line *boggle*.
(get_position_from_xy): this needs to return a utf8 offset.
(e_text_copy_clipboard): convert sel_start/sel_end to byte indices
before copying.
(primary_get_cb): same.
(paste_received): validate the input here, and drop the length
parameter from e_text_insert.
(next_word): convert from an utf8 offset on entry to this
function, and return a utf8 offset when we're done. also, remove
the call the g_unichar_validate. we validate at all points where
text is inserted.
(find_offset_into_line): new function used in the backward/forward
line code. find the utf8 offset into a line (the number of utf8
characters from a prior \n or beginning of the string.)
(_get_position): in general there are lots of changes here because
text->selection_start/text->selection_end are utf8 offsets, not
byte offsets. fix E_TEP_START_OF_LINE so that hitting Ctrl-a when
you're at the beginning of a line doesn't take you to the
beginning of the previous line. fix E_TEP_END_OF_LINE in an
analogous fashion. for E_TEP_FORWARD_CHARACTER we just increment
by 1. for E_TEP_BACKWARD_CHARACTER we just decrement by 1. for
E_TEP_BACKWARD_WORD we drop the g_unichar_validate call and
simplify things a bit. reimplement
E_TEP_FORWARD_LINE/E_TEP_BACKWARD_LINE so they find the current
offset into the line, then scan forward/backward for the next/prev
line, and put us at the right offset on that line. fix
E_TEP_SELECT_WORD so double clicking in the space between words
doesn't select both words - if you double click on the trailing
edge of the space, it selects the next word. leading edge selects
the previous one. for E_TEP_SELECT_ALL use g_utf8_strlen.
(e_text_insert): everything that calls this passes a \0 terminated
string, so we assume it's \0 terminated (the old code did as well,
with calls to strlen) and drop the length parameter. also make
sure this is all utf8 happy.
(capitalize): use g_utf8_offset_to_pointer instead of just adding
text->text and start/end, and remove the validate call. also fix
the call to e_text_model_delete and use e_text_model_insert_length
instead of e_text_model_insert.
(e_text_command): for E_TEP_INSERT, validate the input. for
E_TEP_CAPS just use MAX instead of the neat little hack. also,
fix the scrolling so that it scrolls properly in both X and Y
directions (there are still some hiccups but it's much much better
than previously).
(e_text_commit_cb): validate the input here.
* gal/e-text/e-text-model.c (struct _ETextModelPrivate): just use
a GString here and get rid of MAX_LENGTH.
(e_text_model_dispose): free GString.
(e_text_model_real_validate_position): clean this up a bit.
(e_text_model_real_get_text): return the contents of the GString.
(e_text_model_real_get_text_length): use g_utf8_strlen here.
(e_text_model_real_set_text): convert to GString
(e_text_model_real_insert): just call e_text_model_insert_length
here instead of duplicating the function.
(e_text_model_real_insert_length): convert to utf8/gstring.
i.e. convert @position and @length to a bytes and use
g_string_insert_len.
(e_text_model_real_delete): same, with g_string_erase.
(e_text_model_get_text_length): use g_utf8_strlen
(e_text_model_strdup_nth_object): convert the length of the object
to bytes before copying.
(e_text_model_get_nth_object_bounds): calculate start/end properly
